Your first phone, what does it look like?

I really don't want to mention the embarrassment of buying my first mobile phone, because I'm so stupid that I don't know anything, I just know how to give money. <>

When I bought my first mobile phone was in the second year of junior high school, I took the New Year's money given by the elders to buy a mobile phone in the mobile phone store, the mobile phone at that time was still that kind of straight board, the buttons will flash, and the screens on both sides of the mobile phone will also flash, which is in line with the requirements in my heart at the time, I still remember very clearly, the mobile phone is 440 yuan, for me it is really all my New Year's money, a semester of pocket money, yes, the money at that time was really enough for me to spend a semester.

I still remember that the boss also gave me a mobile phone with a slide, yes, it is a slider, the mobile phone with a slide cover is super beautiful, the buttons are still rotating, I like it, but it is hundreds more expensive than a straight phone, I don't have so much money on me, what is the use of liking it, and the boss said that he would not sell it at a price, and I felt that the boss was really too picky, and I was not cheap for a hundred yuan.

In the end, I had to buy that straight board.,White.,Although the mobile phone without a slider is beautiful but it also meets what you want.,There's no other mobile phone that can get into my eyes.,Because the kind of mobile phone buttons and the screen are flashing on both sides.,bulingbuling,It's also very beautiful.,At the beginning, I was very careful to buy my hands for fear of falling or something.,At that time, I felt like I had a mobile phone that was particularly good.,All day long in class and after class.,Listen to songs with headphones.,Play QQ or something., Although the teacher took away the mobile phone during class time, but those were all trivial things, and they were returned to me in the end, haha!

Now that I think about it, I was really too easily satisfied at that time, and I can only say that I was naïve.

The world's first mobile phone takes 10 hours to fully charge, but the price is more than 60,000.

Do you know what the first mobile phone was for mankind? Take it on the phone like a brick, the price is 50,000

One day in April 1973, a man stood on the street of New York, pulled out a wireless ** about the size of two bricks, and called it, attracting passers-by to stop and look sideways. That man was Martin Cooper, the inventor of the mobile phone. At that time, Coopa was an engineer and technician of the famous American company Motorola.

The world's first mobile communication was played to a rival at Bell Labs, Martin Cooper, 74, who founded his own communications technology research company in Silicon Valley after 29 years at Motorola. Currently, he is the Chairman and CEO of this company. Martin Cooper's idea at the time was to let ** know that wireless communication – especially small mobile phones – is very valuable.

In addition, he hopes to pique the interest of the Federal Communications Commission in supporting Motorola in its rivalry with AT&T, which is also a major communications company in the United States. In fact, going back further, we will find that the concept of mobile phones appeared as early as the 40s. At that time, it was Bell Labs, the largest telecommunications company in the United States, that began trial production.

In 1946, Bell Labs created the first so-called mobile communication**. However, because of its size, researchers had to put it on a shelf in the lab, and slowly people forgot about it. It wasn't until the late '60s that AT&T and Motorola became interested in the technology.

At the time, AT&T was renting out a very large mobile wireless ** that customers could attach to large trucks. AT&T's vision is that in the future it will be able to develop a mobile ** with a power of 10 watts and use the radios on the trucks to communicate with it. According to Coopa, this kind of ** is too big and heavy to move and let people take it with him.

As a result, Motorola applied to the Federal Communications Commission of the United States, requesting that the power of mobile communication equipment should only be one watt, and the maximum power should not exceed three watts. In fact, the radio power of most mobile phones today is only 500 milliwatts at most. From the registration of the mobile phone patent in 1973 to 1985, the first modern sense and truly mobile ** was born.

It is to put the power supply and antenna in a box, weighing up to 3 kg, very heavy and inconvenient, the user has to carry it like a backpack to walk, so it is called "shoulder carry**".
